To all whom it may concern:

Be it known that I, VVILLIAiu Gnouun CLAYTON, a citizen of the (onnnonwealth of Australia, and resident of Upper Hawthorn, near Mellmurne, in the State of Victoria and said Commonwealth of Australia, have invented a certain new and useful Fuel-Economizing Device for lnternal-Conibilstion lilngines. of which the following 15 a specificatiou.

This invention relates to a device for attachment to internal combustion engines whereby the fuel is economized and the starting} of the engine is facilitated.

An essential feature embodied in this invention consists in the particular arrangement whereby hot or cold air forming a secondary or extra air supply is ted as rquired to the cylinder or cylinders of the engine.

A further essential feature mnsists m the use of a chemical strainer or filter for purifving and adding an explosive substance to the secondary air supply before it reaches the cylinder or c 'lindcrs.

ln brrlcr that the invention may be mow HiHlllV understood it will now be described with rcfrrr-nce to thc acc inpan ving drawings. \vlwl'(-l.l--

The invention is directed to the provision of means For the supply or iuterclnuige of hot or cold rhcmirally purilicd air to the engine cyliudcrs to act as a secondary or additional source of air supply to the standardized carlun'eter feed.

According to this invention a flexible metal tube a of the required length is attached at one end by a suitable union or joint to the induction pipe c between the carl'un'cter r! and thrc liudcrs (r.

This flexible pipe o cxf oils from the induction pipe 0 to a pi ition most convenient for operation and cont'roh being preferably passed through the foot plate f and along the steering pillar g to which h ts fastenedj by clips or other fastening devices It.

Adjacent the steering wheel 2' the tubca -is fitted with a control valve which connccts the pipe bend I: to which 18 detachably connected :1 cylinder or container 1 the outer end of which is preferably fitted with ardetachable end or cap m formed with one or a plurality of air holes 11.

W'ithin the cylinder Z a sponge is fitted, preferably two pieces 0 being employed, and a solid piece or pieces of chemical p is also inserted, the chemical unploycd being camplior, saltpeter or other suitable air purifying agent orchemicals containing explosive matter or substances may be used, if desired.

The tube a is preferably lined with asbestos or other suitable heat resisting material.

In operation, and when the engine is running, the suction in the carburetor d is broken to some extent as the tube a is in directcommunication with the atmosphere. A part of the suction from the cylinders e is therefore concentrated through the tube a the supply of air being controlled by the valve The chemical p in the cylinder 1 purifies the air which is drawn past it by the SUCtlOl: created by the engine and the sponges 0 act as a silencer and deaden the noise of the air as it is drawn through the pipe a, the sponges also serving the additional function of ai" iiltcrs or strainers.

When it is desired to supply hot air to the cylinders the. tube on, adjacent the exhaust pipe I is laid. against or alongsideit, St heating the air as it passes through the said tube (a. which tube can readily be removed from the exhaust pipe should cold air be requirod.

By the use of a device for supplying extra hotor cold air to the engine cylinders, than that ordinarily supplied through the carburetor, the cost of running an internal combustion engine is decreased to a considerable tent as more air and less fuel may be used r. .thout decreasing the power of the engine, and the further advantage is gained by the method herein described as the secondary or extra air supply is caused to travel some dis tance. is purified or chemically treated, and is eilectively controlled thus giving the improved results above described.

It will be readily understood that if the chemical used is capable of giving off ex- Ill) plosive gases or substances -the air fed adapted to be connected at its other end to through the device is enriched and consethe engine manifold, a valve between said 15 quent y greater power will be obtained. container and said pipe, the intermediate What do claim as m invention and deportion of said pipe being adapted to be sire to secure by Letters atent isalongside the exhaust pipe of the engine.
